Initial dilution rate: 1 litre dip to 400 litres water.

1 litre dip to 300 litres of top up water after 10% depletion in volume.

Prevents blowfly strike for 8–10 weeks.

1 litre dip to 1000 litres water.

Check that the bath is clean and only use clean water. Fill the dip bath with the required volume of water. If accurately calibrated, fill up to the required mark. To prevent overspill do not fill the bath to capacity and make sure that you allow for water displacement by the sheep. Surge baffles can help prevent spillage. For calibrating the dip bath use a vessel of known volume. It is vital to measure the concentrate and water accurately: DO NOT GUESS. If you are not sure how to do so contact your supplier or seek other reliable help. Thoroughly mix the dip concentrate with the water by carefully stirring it using a metal rod.

Hard water should be softened before use with the dip. You need 1 kg (or 2lbs 3oz) of washing soda to each 500 litres (or 110 gallons) of water and it needs to stand for 2–3 hours before dip concentrate is added.

When dipping for sheep scab all parts of the animal, except the head and ears, should remain under the mixture for at least a minute. Plunge the head under at least twice, allowing time for the animal to breathe between plunges. In confirmed cases of clinical sheep scab, double dipping at an interval of 14 days should be employed. When dipping for blowfly strike, ticks and lice ½ a minute is long enough in the dip bath. Once dipped all sheep should stand in draining pens for no less than 10 minutes. If large amounts of scum form on the surface of the bath skim it off and place in a secure container. This must be clearly marked and disposed of safely.

Top up after the volume of the bath has fallen by no more than 10%. Top up at the required rate.

Fouling of the dip wash reduces effectiveness. Therefore do not dip more than one sheep per 2 litres of dipwash that was in the bath at the start of dipping. For example if the total volume of wash in your dip bath was 1,000 litres (220 gallons) you should not dip more than 500 sheep no matter how many times you have topped up the bath. You should then empty, clean and recharge the bath with fresh dip wash.

If the dip wash is to be retained for use the following day, add two 50 g sachets of bacteriostat per 500 litres of wash AT THE END OF THE DAY'S DIPPING. The sachets in the polythene bag are water-soluble. DO NOT ATTEMPT TO OPEN A SACHET. Simply open the polythene bag, throw the sachet into the bath and allow to dissolve. This releases the bacteriostat into the wash. STIR THE BATH THOROUGHLY to speed the dissolution of the sachet and disperse the wetted powder, so that even distribution of the bacteriostat throughout the bath is achieved. Dip wash is no longer suitable for re-use after 14 days.
